What is the primary function of the Session Layer in the OSI Model?

The primary function of the Session Layer in the OSI Model is indeed managing communication sessions. This layer is responsible for establishing, maintaining, and terminating connections between applications. It enables applications on different devices to communicate with each other in a coherent and synchronized manner, ensuring that data is properly exchanged and that sessions are managed effectively.

The Session Layer also handles session control functions, such as keeping track of which half of the communication is sending data at any given time and managing session checkpoints and recovery in case of interruptions. This is crucial for maintaining the integrity of the communication process across the network.

In contrast, while routing data packets pertains to the responsibilities of the Network Layer, providing physical connection interfaces aligns with the Physical Layer, and establishing data encryption is typically managed by higher layers, such as the Presentation Layer or in conjunction with application protocols. Each layer has its specific functions that contribute to the overall operation of network communication.
